All right… I slowly start to understand (dangerous remark, I know) the advantages of ESS.
I found this post, specifically this line :
The Multi RS will be aware of the loads between the grid and the AC input, and if the Grid meter is correctly configured, and will supply power to them without feeding into the grid.
There is not yet grid code support, so feed-in is not yet permitted.
There is a 10W power draw added from the utility grid: this is a safety margin to compensate for measurement inaccuracies to prevent feeding energy into the utility grid.
So, I can connect the Aircon back to grid, use energy meter to understand how much energy the aircon uses, and let the Multi RS Solar supply that energy (-10w)
Looking at the ESS manual - and updating the first example installation would like :
- My existing Grid inverter - leave as is.
- Move aircon from (now) behind inverter back to grid.
- Enable ESS without feed in option to supply energy to aircon
If I can do that, that is a WAY better way to design what I need.
Question now.. the Multi RS Solar is not (yet) certified for feed-in in Australia. Now, I don’t want to use it for Feed in, but wonder if it still will work? to supply power to the AC loads without feeding into grid?
